Description

発明の詳細な説明Detailed Description of the Invention

本発明は、椎間移植片、特に請求項１に特定される人工椎間板に関する発明である。   The invention relates to an intervertebral implant, in particular an artificial disc as specified in claim 1.

損傷の後、天然の椎間板又は椎間板の髄核は除去され、今のところ、移植片とプロテーゼが隣接する二つの椎間の椎腔へ導入される。このような移植片の移植目的は出来る限り自然の状態にもう一度戻すためであり、具体的にオリジナル椎間板の高さと隣接する椎間のオリジナル間隔を取り戻すためである。さらに、互いに隣接する椎間の相対運動を出来る限り自然の状態でスムーズに行うことである。このために、前方または後方へ曲げる場合に運動の可能性を保持できる本質的要素が脊椎の屈曲と伸展および自然限界範囲内の脊椎の横曲げである。天然靱帯および脊椎に沿う筋肉が基本的に左インタクト（ｌｅｆｔ ｉｎｔａｃｔ）であり、さらに椎間板の機械的交換品の運動を固定する。   After the injury, the natural disc or nucleus pulposus of the disc is removed, and the implant and prosthesis are now introduced into the adjacent intervertebral space. The purpose of transplanting such a graft is to restore it to its natural state as much as possible, and specifically to restore the original disc height and the original spacing between adjacent vertebrae. Furthermore, the relative motion between adjacent vertebrae is to be performed as smoothly as possible in the natural state. For this reason, the essential elements that can retain the possibility of movement when bending forward or backward are the flexion and extension of the spine and the lateral bending of the spine within the natural limits. The muscles along the natural ligament and the spine are basically left intact and also fix the movement of the disc mechanical replacement.

このような椎間移植片はメイセルの独国特許第２０３２０４５４号明細書により開示される。この周知の椎間移植片は骨に連結される二つの覆板と覆板の間に設置される関節機構で構成される。この関節機構は基本的に球状に形成される関節成分と相補的関節殻である第二の関節成分で構成され、覆板が相対的に多軸回転が可能である。この周知の椎間移植片の欠点はＸ線を通さないことと、それにより移植後の隣接する脊椎の観測がもはや不可能なところである。   Such an intervertebral implant is disclosed in US Pat. No. 2,203,454 to Maycel. This known intervertebral implant is composed of two cover plates connected to the bone and a joint mechanism installed between the cover plates. This joint mechanism is basically composed of a joint component formed in a spherical shape and a second joint component which is a complementary joint shell, and the cover plate can relatively rotate in multiple axes. The disadvantage of this known intervertebral implant is that it does not pass X-rays, so that observation of the adjacent spine after transplantation is no longer possible.

本発明はここである医療品を提供する。本発明の目的は、磁気共鳴画像装置（ＭＲＩ）即ちＸ線を透過し、Ｘ線による術後観測が可能で、同時に高いＭＲＩ適合性を有する移植片を提供することである。   The present invention provides this medical product.

発明の内容および更なる展開を、実施例の一部提示図面をもって以下で詳しく記載する。   The content and further developments of the invention will be described in detail below with the aid of a partial presentation drawing of an embodiment.

図１と図２で示される椎間移植片１の実施形態は基本的に、中央軸２に交差し、隣接する上部椎間体の基板に連結する上部接合表面５を有する上部成分３と、隣接する下部椎間体の覆板に連結する下部接合表面７を有する下部成分４および、二つの成分３と４の間に設置され、成分３と成分４を関節的に連結する関節部９で構成される。関節９は二つの成分で構成され、関節部の凸部１２は凸部頂点を中央軸２が垂直に交差するよう球状に構成される。後部１６において、中央軸２に垂直する関節部の凸成分１２の断面は先細になり下部成分４内の凹部１７に押され、中央軸１２を補充する。同様に、関節殻１３は関節の凸状部１２に補充的に設置され、中央軸２に垂直する断面において後部２１が先細になり、下部成分３の補充的凹部２２内に押される。上下部成分３、４および関節殻１３と関節の凸部１２は別個の要素で構成され、上下部成分３、４は例えばＰＥＥＫで作られる。一方、関節の凸部１２と関節殻１３は例えばセラミック材料で作られる。関節の凸状部１２におけるスライディング表面１１と関節殻１３は同じ半径を有する。これにより、関節の凸部１２と関節殻１３との相対運動が可能になる。   The embodiment of the intervertebral implant 1 shown in FIGS. 1 and 2 essentially comprises an upper component 3 having an upper joining surface 5 that intersects the central axis 2 and connects to the substrate of the adjacent upper disc. A lower component 4 having a lower joint surface 7 connected to the cover plate of the adjacent lower intervertebral body, and a joint portion 9 placed between the two components 3 and 4 and articulating the component 3 and the component 4 Composed. The joint 9 is composed of two components, and the convex portion 12 of the joint portion is formed in a spherical shape so that the central axis 2 intersects the vertex of the convex portion vertically. In the rear part 16, the cross section of the convex component 12 of the joint perpendicular to the central axis 2 tapers and is pushed by the concave part 17 in the lower component 4 to replenish the central axis 12. Similarly, the joint shell 13 is supplementarily installed on the convex part 12 of the joint, and the rear part 21 tapers in a cross section perpendicular to the central axis 2 and is pushed into the supplementary concave part 22 of the lower component 3. The upper and lower components 3, 4 and the joint shell 13 and the convex portion 12 of the joint are composed of separate elements, and the upper and lower components 3, 4 are made of PEEK, for example. On the other hand, the joint protrusion 12 and the joint shell 13 are made of, for example, a ceramic material. The sliding surface 11 and the joint shell 13 in the convex part 12 of the joint have the same radius. Thereby, the relative movement of the convex part 12 of the joint and the joint shell 13 becomes possible.

さらに、上下部接合表面は異なる形状を有する。下部接合表面７は凹状に設置される一方、上部接合表面５は凸状に設置される。   Furthermore, the upper and lower joint surfaces have different shapes. The lower bonding surface 7 is installed in a concave shape, while the upper bonding surface 5 is installed in a convex shape.

図３と図４で示される実施例が図１と図２で示される実施例と異なるところは先ず、二つの凹状表面５；７を有するところにある。二つの成分３；４は各自に腹側表面３１；４１、背部表面３２；４２と二つの側表面３３；３４；４３；４４を有する。次に、関節９は上下部成分３；４と接続手段２０によって軸方向に接合される。接続手段２０は固着成分１５を含み、中央軸２と同軸に設置され、ピン２３と後部２４は関節殻１３の頂点を通って、上部成分３と結ばれる。さらに、固着成分１５は大きい半径を有する円盤状エクスパンション２５を含み、ピン２３の前部２６に設置される。関節の凹部１２は穴２８を有し、中央軸２と同軸で、関節の凸部１２の内部にある円筒空洞２９で終了し、円筒空洞２９は大きい直径を有する。固着成分１５および穴２８、空洞２９の形状は、ピン２３が穴２８と空洞２９内のエクスパンション２５の中で可動的に選択される。穴２８の直径“ｄ”を円盤状エクスパンション２５の直径“ａ”より小さくする一方、円筒空洞２９の直径“Ｄ”を直径“ａ”より大きくし、関節の凸部１２および関節殻１３、二つの成分３；４の添付物が関節９の動きに支障がないように軸方向に連結される。穴２８内でのピン２３の可動性および空洞２９内でのエクスパンション２５の可動性により二つの成分３；４の相対的に多軸的回転が可能になる。ピン２３の長さは、穴２８と空洞２９間の移行部の間隔が無くなって始めて関節９が互いに連接し、エクスパンション２５とピン１６の前端２６が連結する。   The embodiment shown in FIGS. 3 and 4 differs from the embodiment shown in FIGS. 1 and 2 in that it has two concave surfaces 5; The two components 3; 4 each have a ventral surface 31; 41, a dorsal surface 32; 42 and two side surfaces 33; 34; 43; Next, the joint 9 is joined in the axial direction by the upper and lower components 3; 4 and the connecting means 20. The connecting means 20 includes an anchoring component 15 and is disposed coaxially with the central shaft 2, and the pin 23 and the rear portion 24 are connected to the upper component 3 through the apex of the joint shell 13. Further, the fixing component 15 includes a disk-like expansion 25 having a large radius and is installed on the front portion 26 of the pin 23. The joint recess 12 has a hole 28, which is coaxial with the central axis 2 and ends in a cylindrical cavity 29 inside the joint projection 12, which has a large diameter. The shape of the fixing component 15, the hole 28, and the cavity 29 is selected so that the pin 23 is movable in the hole 25 and the expansion 25 in the cavity 29. The diameter “d” of the hole 28 is made smaller than the diameter “a” of the disk-like expansion 25, while the diameter “D” of the cylindrical cavity 29 is made larger than the diameter “a”, and the convex portion 12 of the joint and the joint shell 13, 2 The attachments of the two components 3; 4 are connected axially so that the movement of the joint 9 is not hindered. The mobility of the pin 23 in the hole 28 and the mobility of the expansion 25 in the cavity 29 allow a relatively multiaxial rotation of the two components 3; The length of the pin 23 is such that the joint 9 is connected to each other only after the gap between the hole 28 and the cavity 29 is eliminated, and the expansion 25 and the front end 26 of the pin 16 are connected.
